Overall this ontology is just fine, highly suitable for its intended
purpose.  I do have one [hopefully] minor concern. Why is a kayak not a kind
of a boat? The classification in this ontology goes like this:

   - Watercraft
      - Boat
      - Kayak
      - Ship

The source of this (IHMO) mistake may be in the WIkipedia entry for
Watercraft <http://en.wikipedia.org/wiki/Watercraft>:

However, there are a number of
craft<http://en.wikipedia.org/wiki/Craft_(vehicle)> which
many people would consider neither a ship nor a boat, such
as:canoes<http://en.wikipedia.org/wiki/Canoe>
, kayaks <http://en.wikipedia.org/wiki/Kayak>,
rafts<http://en.wikipedia.org/wiki/Raft>
, barges <http://en.wikipedia.org/wiki/Barge>,
catamarans<http://en.wikipedia.org/wiki/Catamaran>
, hydrofoils <http://en.wikipedia.org/wiki/Hydrofoil>,
windsurfers<http://en.wikipedia.org/wiki/Windsurfer>
, surfboards <http://en.wikipedia.org/wiki/Surfboard> (when used as a paddle
board), jet skis <http://en.wikipedia.org/wiki/Personal_watercraft>, underwater
robots <http://en.wikipedia.org/wiki/Robot>,
seaplanes<http://en.wikipedia.org/wiki/Seaplane>,
and torpedoes <http://en.wikipedia.org/wiki/Torpedo>.


Contradictorily, the opening words in the definition of kayak in
Wikipedia<http://en.wikipedia.org/wiki/Kayak>clearly state that a
kayak is a boat:

A *kayak* (sometimes generalised as a *canoe*) is a small
human-powered boat<http://en.wikipedia.org/wiki/Boat> that
traditionally has a covered deck, and one or more cockpits, each seating
one paddler <http://en.wikipedia.org/wiki/Paddler> who strokes a
double-bladed paddle <http://en.wikipedia.org/wiki/Paddle>.

I have been a kayaker for 35 years, and every kayaker I know thinks and
speaks of their kayak as a kind of boat. In the US, most whitewater kayakers
consider themselves boaters.

What competency question justifies this classification?
What is an example of a kayak that is categorically not a boat?
